The resolution of printing matters must be 300 dpi. The color range should be CMYK or RGB.
As file format you can use JPG (JPEG) or TIF (TIFF). If you are using JPG please use a maximum picture quality (minimum compression). We do not recommend PDF!
The music can be send on CD as Audio-CD or WAVE-file via mail or as MP3 or WMA via e-mail attachment. Please note if using MP3 or WMA to convert the music in a high quality to ensure CD sound quality on CD. We recommend min. 192 kBit (MP3) or min. 128 kBit (WMA). The more kBit you set the better the sound will be on CD.
If you are sending the artwork data as e-mail, please, use tools like WinZip or WinRAR to compress TIFF files before you send it through the wire.
If your provider restricts the size of one e-mail send multiple e-mails.
